Specification of Letters Patent.

-'Patented Feb. 26, 1907.

Application filed April 1l, 1906. Serial No. 311.1`76.

To (ir/Z whom, it may concern.-

Beit known that I, GEORGE W. WHITEMAN, a citizen of the United States,residing in Philadelphia, Pennsylvania, lia-ve invented certain'Improvements in Insulated Rail- .Joints, of which the following is aspecification. i

My invention relates to rail-joints, and, while comprising generallyimprovements in .joints having insulating matei'ial disposed between themcbting ends of the rails, it consists of certain improvements in theclass of structures described and claimed in my aps plication for patentfiled September 14, 1905, serai N;'27s,455.

The object of -rny invention `iste simplify to provide up, to prvide asolid metal support for the receiving-'end ofthe rail, and to provide?an a sectional plan View of the same,-t aken on the linea ci, Fig. 3.Fig. 3 is a cross-sectional view, on an enlarged scale, taken on theline?)` b, Fig. 2, illustrating clearly the charactber of my presentinvention.- Fig. 4 is a perspective View of one of the insulatingplates,and Fig., is a perspective-view of one of the wedging members.

. prior application above 4what As in the joint forming the subject ofmy sulation is confined solely to one of the meeting ends of the rails,and inl combination with such insulation and the splice-bars,

may be of the-ordinary type, bent so as to accommodate the same, Iprovide wedging members capable of endwise movement for a limited extentto take up any wear that may occur at this point, such members servingalso to provide a lsolid l metal support for this rail end and havingvsi an upperv flanged portion providinga surfae esgiosedlto theinsulating materialoverlying t e splice-bar that is greater than theundersurfacc of theI rail-head.

@its in tliajoint forming the subject of accordance with my invention.Fig. 2 is referred to, the in prior application -the meeting end of therail nearest the point from which the trallic approaches on such line ofrails is insulated,

which rail l have designated as the receivingrail. In ordinaryjointsthis end of the rail is depressed to a greater or less extenteve time atrain passes over the same, and this depression, especially in the caseof insulated joints, causes a great deal of wear, which must becompensated for, and subjects the bolts'connecting the splicebars to aconside'rable amountv oi tension and, strain. By

tightening up tliewedge blocks employed iii my improved joint I can.take up the wear at this point, and by disposing such vblocks inengagement with the head and base of the In the drawing herewith, 1 and2 represent the meeting'ends of the rails, and 3' the rishplates orsplicebars which are of the ordinary standard type, bent at one end toaccommodate the insulation. Surrounding the rail end 2 is. insulation inthe form of longitudinal pieces 4 of hard rubber, parch- 'mentizedber,or other similar material ,rail AI relieve the strain'on the boltsconncctj ying this portion of the joint.

and a bridge-piece 5 of the same material,

disposed directly between the meeting ends of the rails. interposedbetween the web 6 of the rail end 2, being in engagement with the headand base of the same, and the insulating-pieces 4 are the wedgingmembers 7, the {ish-plates vor splice-bars being extended laterally at8, preferably by bending, to accommodate said insulation and the wedgingmembers. The pieces of insulation are vsubstantially trough-shaped incross-section, and the splice-bars and wedging members have engagingfaces of si rnilar shape, in the present instance the wedging membershaving iianges 9 at the upper portion for engagement with the flange10of the insulating material,

the flanges providing a surface exposed to the insulating materialvgreater than the under surface of the rail-head. y

'l he joint is held in place by the usual bolts 11 and 12, the latterpassing through the. insulated i viith sleeves 13,' of insulatingmaterial. 'ashers 14, of insulating material, are also laced under theusual metal is asliers adjacent the heads and nuts of the bolts i2. Thevwedgingv members are provided with holes 15, through which the bolts 12these holes are elongated, so that said members may be moved endwise'iwhen it is deportion and being provided ICO iro-
